A little nice puzzle
You are given 8 balls. One of the balls is heavier than the rest which are all the same weight. It is impossible to determine the heavier ball by the shape, size or lifting it up. You are given a 2-plated beam balance. Using the balance twice, how can you determine which ball is heavier.

Re: A little nice puzzle
I asked this problem long time back when I was young.
Oh really? Actually I heard this problem from my friend.
